Yeah getting a tetanus jab after stepping on a nail never made a lot of sense to me either. Like trying to buy house insurance while you're house is on fire.

Tetanus was the one pathogen where the immune stimulus matched the infection threat. Getting vaccines for generally non lethal infections always seemed a little retarded. Chicken pox parties over a chicken pox vaccine for example.

It all just reminds me of that guy injecting cow pox pus into his family trying to prevent small pox. Experimenting is cool but to say the science of immunisation has been settled is unscientific.

My kids both have robust immune systems. When they get sick, they get it very acutely & quickly recover. We rarely even get colds in our family.
